L UNITED STATES PATENT OFFICE.

ELIPHALET LESTER ARNOLD,OF CONROE, TEXAS.

CATTLE- GUARD.

SPECIFICATION forming part of Letters Patent No. 628,428, dated July 4, 1899.

Application filed December l, 1898.

To @ZZ whom, it may concern:

Be it known that I, ELIPHALET LESTER AR- NOLD, a citizen of the United States, residing in the neighborhood of Conroe, in Montgomery county, in the State of Texas, have invented a new Improvement in Cattle-Guards, of which the following is a specification.

The guard is all metallic and made in iive sections, all sections alike, each section being seventeen inches wide and six feet long or longer, in the discretion of the party using them. One section is fastened down outside of each railroad-rail and three sections are put side by side between the rails, completing the guard.

'Figure l is a top View of a single section of the guard, and Fig. 2 is a longitudinal section thereof. Fig. 3 is a perspective view of one of its angle-irons. Fig. -1 shows one of the plates used to connect the angle-irons.

Similar letters refer to similar parts throughout the several views.

The angle-bars will stand three inches above the ties when fastened. These bars have at each end on the bottom flange two round holes K K and these holes are used to receive rivets to fasten the strips of sheet-iron N N. The round holes H H receive two round rods M M, each of said rods being seventeen inches long, which are expanded slightly on the outside. These rods are of five-eighths round iron and are intended to tie the angle-bars together and to be put just high enough in the angle-bars to lift the bottom side of the hoop-iron bands D D up to within threefourths of an inch of the bottom side of the round journal-rods C C. The top edge of the angle-bar is provided with slots SS, made U-shaped or square at the bottom, either of which shapes will do. In the slots S S rest the journal-rods C C, which are of five-eighths round iron eighteen inches long, grooved slightly, close at the end to slip down in slots S S. On journal-rods C C revolve eleven toothed wheels E E, made of sheet-iron oneeighth of an inch thick and four and one-half inches in diameter, each toothed wheel to contain ten or more points or blades, the points or blades to be square-cornered and sharp on edges, which shape or design of the points or blades constitutes the peculiarity serial No. 697,990.v (No man.)

of the wheels. The number of wheels to each journal-rod will be eleven. The exact size of these wheels will be governed by the height of the railroad-rail.

Near the end of the angle-irons are tWo slots .I .I in each angle-bar, one at each end, to receive eccentric-rods B B, which are made round where they work in the slots, but just outside are square to receive an S-wrench. These eccentric-rods will be of wrought or cast iron, each made with a long side, and they will be placed in position with the long radii turned toward each other from both ends of the gap. Hoop-iron bands D D, one and seven-sixteenth inches Wide, encircle eccentric-rods B B and journal-rods C C. The bottom of the bands D D rest on the top of the rods M M. A band is placed between each line of toothed wheels, ten bands in each section. The bands are made just long enough to allow the eccentric rodsV and journal-rods to be lifted out when the long radii of the eccentric-rods face each other in the event the section-men wish to slip on a new toothed wheel if broken orto clean them on the under side should mud or snow accumulate. The bands are made taut by using two S-Wrenches, turning the long radii of the eccentric-rods B B from each other and down until the long radii of the eccentricrods rest on the base-plate of the angle-iron. The eccentric-rod is a tightening device to make the hoop-irons tight or loose, as desired. The bands are for two purposes. One is to hold the toothed wheels in perfect line and perpendicular when stepped on by stock. The other purpose is to' render the gap easily cleaned by the use of a paddle between each line of toothed Wheels.

What I claim as new, and for which I desire to procure Letters Patent, is-

1. The combination of the angle-irons A, held together by plates N and rods M, with rods C, toothed wheels E carried by said rods; eccentric-rods B, resting in slots at the ends of the angle-irons; and hoop-iron bands D, encircling all the rods and separating the wheels, substantially as shown.

2. A cattle-guard consisting of sections, each composed of angle-bars held together by plates N and rods M, and having bearing- IOC) slots in their upper sides and at their ends; in the presence of two Witnesses, this Novemrods C carried in the lateral slots, Wheels E, ber 28th, 1898.
